As mentioned, the drag equation with a constant drag coefficient gives the force experienced by an object moving through a fluid at relatively large velocity (i.e. high Reynolds number, Re > ~1000). This is also called quadratic drag. The equation is attributed to Lord Rayleigh, who originally used L in place of A (L being some length). WebMar 1, 2024 · Credits: NASA. This article is part of the NASA Knows! (Grades 5-8) series. Aerodynamics is the way objects move through air. The rules of aerodynamics explain how an airplane is able to fly.
